Ability to distinguish between causal (cause-effect) and teleological (means-ends) explanations was measured in 1905 twelfth-grade biology students and found to be dependent on student knowledge. Although the inability to make these distinctions contributes to misconceptions in biology, appropriate instruction can easily remedy the problem. Sample…

Sixteen concept words related to "matter" were described as simple textbook definitions and 16 multiple-choice items were constructed for each concept definition. These materials were used to compare the ability of 1,635 Tasmanian and 826 Indian students to recognize the concept definitions and their attendant verbal labels. (JN)

Developed and validated a learning hierarchy for the concept "food web" (the hierarchy consisting of nine skill areas). Also investigated the misconceptions of 200 students related to these nine areas. Suggestions for applying the hierarchy model to remediation and resolution of the misconceptions are provided. (DH)

Investigated the meaning that Hindi-speaking students (N=826) in India and English-speaking students (N=1,635) in Tasmania preferred when thinking about each of 16 key concept definitions associated with the theme "the nature of matter." Results show marked changes in the development of these preferences which raises issues for science…

Investigated (1) conceptions 40 African students used in solving floating/sinking problems; (2) nature of these conceptions; (3) kinds of arguments of epistemological commitment they displayed in their responses; and (4) if their conceptions differed from scientific conceptions. (JN)

Three high school biology textbooks were analyzed to determine possible sources of misconceptions and related learning problems associated with genetics. Misconceptions were examined in these categories: conceptual organization; conceptual relations; use of terminology; and mathematical elements. Implications for instruction related to each…

Investigated common belief patterns secondary school students (N=84) have about inheritance, noting the most prevalent misconceptions about genetics which occur at different age levels. Implications based on findings and suggestions for teaching lower secondary courses are included. (ML)

The interview-about-instances technique was used to investigate the conceptual frameworks that 17 Form Four Southeast Asian students held about forces acting on an object at rest or in motion. Results show a number of alternate frameworks which are similar to those found in research conducted in western countries. (Author/JN)

Investigates the effect of modeling analogy on learning of the concepts of electricity in grade 6, 8, and 10. Describes 2 analogies (train analogy and thermal analogy) with diagrams and examples. Discusses the accessibility, transferability, and difficulty of each analogy. Reports treatment effect and some further implications. (YP)

Clinical interviews were conducted with 25 seventh- and eighth-grade students to determine: (1) the extent to which they could produce correct graphical representations of familiar situations; (2) to what extent they could infer relationships from graphs; (3) what are the most commonly held graphing misconceptions and how stable they are; and (4)…

In most research that investigates factors influencing the success of analogies in instruction, an underlying assumption is that students have little or no knowledge of the target situation. It is interesting to ask what factors influence the success of analogies when students believe they understand the target situation. If this understanding is…

Several categories of misconceptions which appear to be emerging across studies are discussed. They include: mis-perceptions; stunted conceptions; mis-translations; confused conceptions; lost conceptions; and true misconceptions. True misconceptions are metaphors and analogies which represent truly complete systems of explanation but are…

This study investigated how students processed information obtained by reading a passage related to inertial reference frames. Two groups of 10th-grade students (one group consisting of students identified as potential National Merit Scholars and another consisting of students enrolled in level-I biology) read a science text passage and answered a…

A number of alternative frameworks used by 84 students (ages 12-16) in interpreting phenomena concerned with fluid pressure were identified during interviews with these students. Methodology employed, tasks used to obtain data, an analysis of the results, and implications for physics teaching are included. (JN)

The level of meaning (membership, partial association, or generalization) that English-speaking (N=1635) and Hindi-speaking students (N=823) preferred when thinking about each of 16 key concept definitions associated with the theme "the nature of matter" was measured for each concept. Results and implications for science instruction are…
